Nothing to work with? Ha. You're clearly a novice-level player. Despite you banning me from the Doubles room on Pokemon Showdown!, I will help you out. With Vespiquen, there are two different methods to use. The first method is what I like to call "Pure Domination". With this method, you basically send in Vespiquen and OHKO all of the enemy Pokemon. The second method, and my personal favorite, is the "Strike Fear in the Enemy" method. With this method, you send in Vespiquen, use any move, and the opponent will forfeit the battle right after. Here is the best set, in my opinion, to use.

This set works for both methods. Good luck in your future battles, trainer.
